It is so difficult that actually method of chemical industry off-gas treatment is done not have, no more than is the following!

Chemical industry calls chemical treatment industry again, show in producing a course, chemical method takes the process industry of main position. Include material of basic and chemical industry and organic raw material, synthesis, pesticide, dye, coating, dye and coking plant industry to wait.

Main component is the waste gas that these industry produce in the process that machines production: Flammability organic waste gas, contain the chloridize hydrogen waste gas, waste gas that contain fluorine, contain vulcanization hydrogen the waste gas, firedamp that contain fluorine and contain chloric ethane, coating to produce waste gas of waste gas, inorganic pigment.

The processing technique of these chemical industry waste gas is:

One, flammability organic waste gas: 1. Direct combustion law 2. Law of heating power combustion 3. Catalytic combustion law 4. Adsorptive, absorb a law.

2, contain chloridize hydrogen waste gas: 1. Condensation law 2. Water absorbs a law 3. Counteract absorb a law 4. Glycerine absorbs a law.

3, the waste gas that contain fluorine: 1. Counteract a law 2. Oxidation is reductive law 3. 4 chloridize carbon absorbs a law 4. Vitriolic ferrous or chloridize ferrous solution absorb a law.

4, contain vulcanization hydrogen waste gas: 1. Hydrogenous oxidation natrium absorbs a law 2. Hydrogenous oxidation calcium absorbs a law 3. Brimstone of combustion legal system 4. Make 2 armour sulphoxide.

5, contain chloric firedamp and chloric ethane waste gas: 1. Use condensation – dry – condensation craft.

6, coating produces waste gas: 1. Derv absorbs a law 2. Law of activated carbon adsorption 3. Catalytic combustion law 4. Law of negative pressure condensation.

7, inorganic pigment waste gas: 1. Water absorbs a law 2. Wet absorb 3. Rare lye absorbs a law.
